                INFORMATION REQUIRED IN REGISTRATION STATEMENT

ITEM 1. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

      This Form 8-A is being filed by Thermo Electron Corporation to reflect the
fact that it has assumed the obligations of Thermo Instrument Systems Inc. under
its 4%  Convertible  Subordinated  Debentures due 2005 (the  "Debentures")  as a
result of the merger,  effective  June 30, 2000, of Thermo  Instrument  with and
into Thermo Electron. Information concerning the Debentures registered hereunder
is included in the sections  captioned  "Description  of Debt  Securities of the
Company  and  the  Guarantees"  in the  prospectus  dated  August  1,  1997  and
"Description  of Debentures and the  Guarantees"  in the  prospectus  supplement
dated January 15, 1998,  which  prospectus and prospectus  supplement were filed
with the Commission under Rule 424 as a part of Thermo Instrument's Registration
Statement on Form S-3 [File No. 333-32031 and  333-32031-01],  which information
is incorporated by reference herein. In addition,  as a result of the merger, in
which holders of Thermo  Instrument common stock (other than Thermo Electron and
stockholders  properly  exercising  appraisal  rights)  received  0.85 shares of
common stock of Thermo  Electron in exchange for each Thermo  Instrument  share,
the  Debentures  are now  convertible  into Thermo  Electron  common  stock at a
conversion price of $41.94 per share.
